Product Details

Nappy Overview

Thirsties One Size All in One is just as simple to use as a disposable. The nappy comes with  a built-in, three-layer microfiber terry soaker absorbs an amazing seven times its weight in liquid. The soaker is sewn in on one side (at the top of the diaper), which makes adding extra absorbent layers a cinch and tremendously decreases drying time. A trim fit nappy and offers gentle elastic around the legs and waist to protect against leaks.


All In One is a birth to potty nappy thats designed to fit from 8-40lbs.

How do I use it?

Simple to use. All in one piece with sizing poppers to the front of the nappy making it adjustable for your baby's different stages.

Nappy Fabric

The nappy comes with  a built-in, three-layer microfiber terry soaker absorbs an amazing seven times its weight in liquid. The soaker is sewn in on one side (at the top of the diaper), which makes adding extra absorbent layers a cinch.


The soaker is topped with our stay-dry microfleece which keeps your baby feeling dry. An additional layer of terry lies between the microfleece and TPU body of the diaper providing a last line of defense. The soaker is sewn in on one side (at the top of the diaper), which makes adding extra absorbent layers a cinch and tremendously decreases drying time…it’s the fastest drying diaper we’ve ever created!

The nappy fits from 10-35lbs

Thirsties Care Guide

  • Wash all nappies once before use. Prewash any hemp products separately for at least 3 times. The hemp will reach full absorbency after approximately 8 washes.
  • Wash dark colours separately
  • Wash with non-bio powder
  • No harsh stain removers or bleach. They may cause irritation and can damage the waterproof membrane
  • Don't use pastes of nappy powder directly applied to nappies as this is too concentrated.
  • No fabric softeners. They will reduce absorbency.
  • Rinse nappies prior to main wash. Or Prewash (small amount of detergent optional) but this will subject the nappies to more 'wear and tear'
  • Main wash with max wash temperature 60 degrees.
  • Line dry. Can be tumble dried on low, but ideally no more than once a month to prevent premature deterioration to the nappy.
  • If using a nappy cream always use a nappy liner - ideally a disposable paper liner.

Thirsties offers a 1 year guarantee against manufacturing faults. The 1 year guarantee starts from when the item was purchased, not first used. If you believe you have an item with a manufacturing fault, you will need to contact us with details and photos of the fault. We will confirm your purchase date from our records. Thirsties may require the items to be inspected before a warranty decision is made, we will inform you if this is required in your case.  Thirsties warranty decision is final.

Thirsties Warranty is VOID when:

  • Using harsh stain removers, biological detergents or bleaching
  • Continually tumble drying on a warm or hot heat, or directly on radiators or similar
  • Adding vinegar or sodium bicarbonate to the wash

Excessive laundering can destroy elastic, destroy the water repellency, make the fabric go bald, reduce the performance of your nappies, drastically reduce the lifespan and will render your guarantee void. 

Thirsties' decision on any warranty claim is final.

So soft, but unimpressed with functionality so far.
15 November 2021  | 

I love the pattern and the fluffy inside, which I imagine must feel lovely against my baby's skin. They also air dried very quickly in my flat. However, compared to other all-in-one styles I find the design of these lacking because the absorbent inner and waterproof outer are joined in the outside seam. This seemed to cause liquid to be wicked onto baby's clothes each time we used them. They are also much more bulky than other styles I tried. I'll still use the one I own, but I don't think I will buy any more of this style.

Very quick drying
13 October 2020  | 

Very quick drying and good absorption.
On the downside, I find it too “fleecey”: it doesn’t look like the skin can breathe well.

Not absorbent enough
12 June 2020  | 

This nappy leaked within 45 minutes of putting it on. I have other microfibre nappies that are much more reliable.

Good, easy to use
20 May 2020  | 

This was one of the nappies recommended to us. It’s very easy to use, and dries very fast. It’s not as absorbent as other nappies, but it’s one of the softest against her skin. I wish there was a Velcro version however. We are planning to buy more of this nappy as we found it the best for us.

Narrow gusset
07 February 2020  | 

On its own, a nice slimline nappy. The gusset is a bit narrow to accommodate a booster and I don't trust it without so tend to use only for short periods, e.g. before bed time

Tendency to leak - not good for active babies
22 January 2020  | 

These were our first go at cloth nappies and purchased following a recommendation from the nappy lady. Unfortunately they have been disappointing. The fit is very small when compared to others and we have experienced constant leaks. Especially when my little one crawls about when wearing them, when he sits down in them or is in the sling. All in all they don't tend to last more than an hour or two.

The positives are that they wash well and are quick to dry.

Easy to use
06 January 2020  | 

Very absorbent, quick to dry and so easy to use. The only downside is that it is quite bulky on my 3 month old so she has to wear larger sleepsuits to fit over the nappy . Not had a leak from these so far and her bum stays feeling dry even when nappy is full .

A new favourite
05 November 2019  | 

I can't believe how ready these nappies are to use. Each time I try a new brand I find it takes me a while to get the fit right but these are just amazing. Looks really slim even with the tongue folded at the front and no leaks after 3 hours which is amazing for my heavy wetting boy! Dries really fast too.
Only slight concern is that the material on the inside already looks a tiny bit bobbly, I wonder how it'll look after a couple of years of use.

Overall a very good nappy and I would love to try more!

Not my favourite
25 October 2019  | 

We were recommended these as one of the options after taking the site's questionnaire. I'm glad I only bought one to try as I find I get leaks much quicker than other brands, sometimes within 1-2 hours even when boosted. The inside of the nappy also went very bobbly after the first couple of washes (although hasn't got any worse in the months since). I tend to only use this when I know it will only be on an hour or so, e.g. at the end of the day. The fit looks good but just doesn't seem to suit us.

Good but not great
15 October 2019  | 

I find the fit of these nappies a bit strange on my son as they seem to be a bit thin at the front so we get leaks (he is a very chunky baby!). It took us a long time to figure out the right configuration of poppers to make them work for us but now it is a bit better. In general, I find the poppers a bit fiddly as there are 3 on each side, I prefer velcro.

However, they are absorbent for daytime and they appear to be quite comfy.

I bought the little lamb onesize nappy at the same time as these and for half the price I think I prefer that one over the thirsties.

Love this nappy
08 October 2019  | 

Big fan of this nappy - trying to find an alternative to the sold out everywhere bumgenius freetime and have not got on well with the TB easyfit or bambino Mio solo. So happy to have found this nappy it fits well lasts 4 hours without boosting and dries really quickly. Best of all it's not too expensive. And lI love the patterns. One happy nappy customer

Great fit but not the most absorbant
26 September 2019  | 

I do like these nappies, but here we only use them as back-ups or when baby needs a change say at 4:30 and bath time is at 6. I wouldn’t trust them for long period of times and I’ve had to boost them straight away. My little one is 7 months old and uses unboosted unos and blueberry simplex.
They’re still really good though - soft, seem comfy and dry very quickly!
Amazing service from the nappy lady, as always!!

Good value for money
23 April 2019  | 

It’s a very good value for money nappy, as it is a bit cheaper than other AIOs, but works very well and dries quickly. However, it does look a bit worn down already after using it for a month. But that aside, a very good nappy.
